[Greenlight photoselective vaporization prostatectomy versus thulium laser vaporesection of the prostate for aged high-risk BPH patients with the prostate heavier than 80 g].

Objective: To compare the effects of greenlight photoselective vaporization prostatectomy (PVP) and thulium laser vaporesection of the prostate (TmLRP) in the treatment of aged high-risk BPH patients with the prostate weighing > 80 g.

Methods: We included in this study 118 high-risk BPH patients aged 62-96 (mean 76) years with the prostate heavier than 80 g, 82 treated by PVP and the other 36 by TmLRP. Then we compared the operation time, intraoperative bleeding, complications, short-term effectiveness, and surgical cost between the two groups.

Results: All the patients tided over the perioperative period without blood transfusion and serious complications. The mean operation time, postoperative bladder irrigation time and surgical cost were significantly less in the TmLRP than in the PVP group (P < 0.05). Both the procedures remarkably improved the international prostatic symptom score (IPSS), quality of life (QOL), post void residual urine (PVR) and Qmax of the patients (P < 0.05), but with no significant differences between the two groups (P > 0.05).

Conclusion: Both PVP and TmLRP are effective and safe for the treatment of aged high-risk BPH patients with the prostate heavier than 80 g, but the latter is superior for its shorter operation time and lower surgical cost.
